Add support for multiply calling lambda parsers in Clara

Browse Source 
Previously a lambda parser in Clara could only be invoked once,
even if it internally was ok with being invoked multiple times.

With this change, a lambda parser can mark itself as `accept_many`,
in which case it will be invoked multiple times if the appropriate
flag was supplied multiple times by the user.
